ANDREAS P. MILLSPAUGH, OF DARIEN, CONNECTICUT.

WAGON-JACK.

SPECIFICATION forming part of Letters Patent No. 384,705, dated June 19,1888. Application filed March 22, 1888. Serial No. 268,076. (No model.)

To all whom it may concern.- H is the axle-support, and is notched as Beit known that I, ANDREAS P. MILLS- PAUGH, a citizen of the UnitedStates, residing at Darien, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements in Wagon-Jacks; and I do hereby declare the following to be a' full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has reference to carriage and wagon jacks, and has for itsobject to provide such a device as shall be readily adjustable to theheight of any ordinary axle, while at the same time great liftingpoweris obtained without undue strain on the operating parts of the device;and with these ends in .view my invention consists in the details ofconstruction and the combination of elements hereinafter fully setforth, and then specifically designated by the claim.

Referring to the accompanying drawings, Figure l is a sectionalelevation of my improvement, and Fig. 2 a section at the line at so ofFig. 1.

Similar letters denote like parts in both figures.

Theframe of my improved jack is formed by two uprights, A, projectingupward from a base, B, and a cross brace, C, extending.

from said base and bolted to said uprights between the same.

D is the operating-lever the inner end of which is formed into a cam, E,which is pivoted between said uprights.

F are side plates secured to opposite sides I shown at I, and extendswithin the hollow lift G. V

J is a yoke extending around said support and having a tail-piece, K,which latter has teeth L adapted to fit within the notches I.

In assembling the several parts of my improvement, the support is placedwithin the hollow lift, so that the yoke J rests against the top of saidlift.

It should be mentioned that the yoke is wider than the diameter of theopening in the I thereby also elevating the support H, and

when the lever is thrown upward the several parts will return to'normalposition by gravity. Having thus described my inventiomwhat I claim is-In a wagon-jack, the combination, with a slide-lift adapted to be raisedand lowered, of

a notched axle-support interior of said lift, and a yoke supported bysaid lift and having teeth adapted to engage with said notches, wherebysaid yoke and support are secured together in various adjustments,substantially as and for the purposes hereinbefore set forth.

In testimony whereof I affix my signature in presence of two witnesses.

ANDREAS P. MILLSPAUGH.
